Funny, I don't seem to be familiar with "House of Dracula" from 1945. I've never cared for the original "Dracula" with Bela Lugosi, even thought the screenplay, I believe, was by John Balderston, who adapted a Henry James novel as "Berkeley Square." But I had read the novel at a young age and no movie ever came close to doing it justice.
I enjoyed revisiting two of the Lee Hammer Dracula movies on TCM, too, and hastened to make certain I had all of them on DVD (had to order "Scars of Dracula" and "Satanic Rites of Dracula" to complete my library.
